The fan will work to send hot air into the inner tank, and the air in the inner tank will be discharged from the air outlet. At this time, the interior of the inner tank is in a high humidity and high temperature environment. Therefore, the effect of the hot air drying in the early stage is not obvious, and there are problems of high energy consumption and waste of electricity.

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0021] Please see Figure 1-3 The present application provides an inner liner ventilation and drying system, which includes an inner liner 1 and a door body 2, the door body is used to seal the opening on the front side of the inner liner, the inner liner is provided with an air inlet shell 3 and an air outlet shell 4, the air inlet shell is provided with an air inlet fan 5 and a first heating element 6, the air inlet fan is arranged on the air inlet end of the air inlet shell, and the output end of the air inlet shell is communicated with the interior of the inner liner 1; the air outlet shell 4 is provided with an air outlet fan 7, the air inlet end of the air outlet shell is connected to the inner liner 1, and the air outlet end of the air outlet shell is communicated with the outside; the door body 2 is provided with an air shell 8, the air shell is provided with a circulation fan 9 and a second heating element 10, the door body is provided with a first interface and a second interface corresponding to the interior of the inner liner, the air inlet end of the air shell 8 is connected to the first interface, and the air outlet end of the air shell is connected to the second interface, and a circuitous condensation air duct 11 is formed inside the air shell, and the air shell is arranged on the door body, so as to make full use of the internal space of the door body, and to avoid damaging the inherent structure of the inner liner by being arranged on the inner liner, so as to avoid affecting the structural stability and sealing of the inner liner. After the dishwasher has washed the dishes, the second fan works to lower the temperature and humidity inside the inner tank. At this time, only one fan is working and there is no heating element. Its power consumption is low, which saves electricity and can help the later heating and drying stage.
[0022] The condensation air duct 11 is arranged horizontally and circuitously from top to bottom. This structure enables the condensation air duct to have a larger condensation contact area for air to contact and produce condensed water. The inlet of the condensation air duct corresponds to the air inlet end of the air shell 8, and the circulation fan 9 is arranged at the outlet position of the condensation air duct. The second heating body 10 is located on the air outlet path of the circulation fan.
[0023] The wind shell 8 is provided with a first water return port at the outlet position of the condensation air duct. The first water return port is connected to the air outlet end of the wind shell through a first water return pipe 12. The horizontal height of the first water return port is higher than the air outlet end of the wind shell. The condensed water generated in the condensation air duct will flow along the condensation air duct to the first water return port, and then be discharged to the air outlet end of the wind shell through the first water return pipe, and then directly flow into the inner tank.
[0024] The inner tank 1 is provided with a respirator 13, which is connected to the inner tank. A connecting port is provided on the respirator, and an air outlet end of the air inlet shell 3 is connected to the connecting port to achieve communication with the interior of the inner tank 1. The respirator is a necessary component of the dishwasher. The air inlet shell is connected to the respirator to achieve communication with the inner tank, which can avoid drilling an additional hole in the inner tank for connection with the air inlet shell.
[0025] The horizontal height of the air outlet end of the air outlet shell 4 is higher than the air inlet end of the air outlet shell. A second water return port is provided at the air outlet end of the air outlet shell. The second water return port is connected to the air inlet end of the air outlet shell through a second water return pipe 14. The air discharged at the end of the air outlet shell may generate condensed water at the air outlet end. The condensed water can be guided back to the inner tank by the second water return pipe.
[0026] The air inlet housing 3 and the air outlet housing 4 are respectively arranged on the left and right walls of the inner container to avoid the air inlet housing and the air outlet housing being arranged too close to each other to affect the external circulation of the air in the inner container.
[0027] The present application also provides a liner ventilation drying method, which has the above-mentioned drying system, and the drying method is specifically as follows:
[0028] In the first drying stage, the circulating fan 9 is turned on and the air in the inner tank 1 enters the condensation duct 11. After the air enters the condensation duct, condensation water is generated, thereby reducing the air humidity. The air then returns to the inner tank from the air outlet end of the wind shell, realizing the internal circulation of the air in the inner tank. In this stage, the working time of the circulating fan 9 lasts for 15-20 minutes, and then enters the second drying stage. Within this time range, it can be ensured that the air temperature and humidity in the inner tank are reduced, avoiding the waste of electricity caused by direct heating and drying at the beginning.
[0029] In the second drying stage, after the first drying stage, the temperature and air humidity inside the inner tank have dropped, and the air inlet fan 5, the first heating element 6 and the air outlet fan 7 are turned on. The outside air enters from the air inlet shell and enters the inner tank after being heated by the first heating element. Then the air in the inner tank is output from the air outlet shell to realize external air circulation, and the input hot air can dry the tableware.
[0030] Furthermore, in the second drying stage, the circulating fan 9 is turned on to continue to circulate the air inside the inner tank, so that the air in the inner tank continues to condense in the condensation duct 11. Since the first heating element is working, the air temperature inside the inner tank increases. In this case, the air circulating in the inner tank again can continue to produce condensed water, which can effectively shorten the drying time of the tableware.
[0031] Furthermore, in the second drying stage, the second heating element 10 is turned on to circulate and heat the air in the inner pot, thereby enhancing the drying effect on the inside of the inner pot 1. With the cooperation of the first heating element and the second heating element, the inner pot can be dried very quickly and the tableware can be dried.
[0032] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
